Management involves coordinating efforts to accomplish goals using available resources. It includes planning, organizing, staffing, leading, and controlling. Management can be applied at different levels, such as for individuals, organizations, or projects. Within organizations, there are typically three levels of management - top level determines objectives and policies, middle level executes plans and coordinates departments, and lower level directs workers and maintains morale. Effective management at all levels through visualization, organization, planning, and utilization of resources can help achieve desired objectives.
